This invention pertains to the general class 'of devices ada ted for use with cooling apparatus of a re rigerator car and articularly to a brine valve mechanism there or. An ob- 'I ject of a plicants invention is the production of a rine valve and means for operating same that are simple in construction, of a small number of parts, positive in operation, readily installed, economical to manufacture l0 and fool-proof. A further object of applicants invention is the production of a brme valve mechanism by means-of which a quick discharge of the brine may further object of applicant s invention is the l production of a brine valve mechanism which v o rates in a manner to prevent dampenlng o the felt insulation within the car, corrosion of the under-frame, and dripping along the tracks. A further object is the production 20 of a device of this character which will not readil become clogged and is easily opened should7 any obstruction occur. Many other objects and advantages of the construction herein shown and described will be obvious to *5 those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, 30 and more particularly pointed out in the claims. p

In the drawings, wherein like reference characters indicate like or corresponding parts: O

Fig. 6 1s a section on line 6'-6 of Referring now to the drawings, in 1g. 1, 1 shows a refrigerator car having a plurallty of ice tanks 2, 3, 4 and 5 arrange in pairs on each side of the car. Tanks 2 and 3 have a be eiected. A

common brine valve mechanism 6 and tanks 4 and 5 have a common brine valve mechanism 7. The mechanisms 6 and 7 are duplicates the first being shown with the operating rod 8 1n open position and the second with the operating rod 8 in closed position. In addition to the .operating rod 8, each brine valve mechanism comprises a valve body 9, a pi 10, tank nipples 11 and 12 connected to tang: 2 and 3 respectively, hose connections 13, 14 5 and 15, a discharge pipe line 16, and an operating rod guide bracket 17.

The interior of the valve body is shown in Fig. 3. Pipe is shown connected to the upper portion thereof by means of a fla member 18 which is internally threaded at 19 to accommodate the pipe 10. Operating rod 8 extends upward through the pipe 10 and has attached to the bottom thereof a tapered plunger 2O which in the preferred embodiment is of cast iron. The plunger 20 is preferabl threaded on to the rod 8 -or otherwise suita liv secured thereto, and has preferably secure to the bottom thereof a beveled rubber valve washer 21 which is locked on the 75 o erating rod 8 together with the tapered p unger 20 by means of a washer 22 and a burr 23. This valve Washer is referably formed with a double bevel on its e as shown. The tapered plunger is preferab y formed with a portion of uniform diameter 24 and the tapered portion 25. The shape of the tapered portion 25 is such as to conform to the tapered seat 26 of the valve bod 9. The rubber washer 21 is preferably o? a size such that its beveled ed e will engage the conical seat 26 first, thus olding the conical portion 25 of the plunger away from the seat, only allowing same to engage when the rubber washer is worn or otherwise displaced. The conical portion 25 thus comes into actual contact with the seat only in case of an emergency, same under normal conditions wedging the tip 21' of the valve washer against the seat 26. At each side of the valve body 9 are the hollow projections 27 and 28 over which fit the hose connections 13 and 14 respectively.

Hose connections 13 and 14 also connect to tank nipples 11 and 12 respectively. The tank nipples are shown more clearly in Figs. 5 10 and 6. The tank nipples 11 and 12 are provided with tubular portions 29 and 30,over which the hose connections 13 and 14 fit.

Each tank nipple is provided with flanges 31 and 32 respectively which engage tanks 2 and.

ward below the channel 38 of the nip le.

extension and secured in Nip le 11 is used as an illustration in ig. 6. 'fille purpose of this construction is to prevent chips and sticks of wood and other forf eign matter floating on top of the brine from passing throu h the channel 38 and into the valve body 9. ank nipples 11 and 12`may be secured to their respective tanks in an suitable manner such as with solder or Wity bolts or any other suitable means. The valve discharges outward through the pipe line 16 which is connected to the valve body by means of the hose connection 15. Pipe line 16 is bent preferably at 37 and extends downward through the bottom of the car as shown at 38' and is preferably provided with an additional angular portion39 in order that the brine when discharged will not come in contact with the underface of the car.

The pipe 10 at its top is secured to an extension 40 on the operating rod guide hanger bracket 17 preferably by means of wire bands 41 and 42 passing around the pipe 10 and the lace by the fingers 43 stamped or otherwise ormed at the bottom of the extension 40. The operating rod guide bracket has preferably a base por` tion 44 to which the extension 40 is attached and side wings 45 and 46 which pass between the members of the center bridging 47. The side wings 45 and 46 have outwardly and downwardly extending angular ortions 48 and 49 respectively which hoo over the members of the center bridging 47. The operating rod 8 is provided with an offset portion 50 and a handle portion 51. The wings 45 and 46 with their angular top portions constitute spaced hanger members for engaging frame members of the car to sus end and firmly support the tubular guide t erefrom, and this supporting of the tubular guide and the valve from the frame members of the car will relieve the hose connections 13 and 14 of strain incident tothe weight of the tubular member and to vibration resulting from train motion. The angular downwardly extending portions 48 and 49 form substantially hookshaped portions for engaging the frame members of a car, and the space between the hanger members guides the upper portion of the operating rod and will prevent rotary movement of the same when the valve is in'its closed position.

TheV operation of the device is as follows:

After removinthe hatch plug, the operat' rod 8 is raised y means of its handle 51 an is turned so that the offset portion 50 rests upon the center bridgin 47. In thisp'osif tion the plunger 20 and t e rubber washer 21 and the plunger 2O to their original closed peosition. In this position the tip 21of the veled portion is wedged between the conical portion 25 of the plunger and the seat 26.

Fresh ice is then placed in the tanks. 4Of course it is understood that other forms of valve washers may be used.

It will be noted that with applicants novel construction the valve member cannot bev left open after icin inasmuch as the handle 51 projects upwar when the valve is in the open d position to such Van extent as to prevent replacing of the hatch plug. The pipe 10 not only serves as a guide for the operating rod 8 'y but is also a standpipe whereby a hea is always maintained on the outlet in the valve same being of suicient height to prevent water flowing over the top thereof.

With applicants novel construction the tanks in the car can be drained within three or for minutes, thus eifectin a great savin of time. Should the valve become cloggve same is readil cleaned by means of removing the rod 8. owever clo ging of the valve is prevented not onl b the novel mouth for the nipples, but a so the smooth contour of the valve seat, there ing no shoulders lon same.

The ordinary pans which are installed in refrigerator cars are not used except for the collection of sweat from the tanks, thus clogging of same is avoided inasmuch as no sediment settles in same. All sediment from the lbrine tanks is carried out directly through ap licants novel valve mechanism.

aving thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
